' EDWIN ADAM'AND MARTIN O. REHFUSS, OF PHILADELPHIA, PENNSYL- VANIA,ASSIGNORS TO EDWIN ADAM, OF SAME PLACE.

CHARGING AND COMBINING WORT, L IQUORS, &c., WITH CARBONlC-ACID GAS.

SPECIFICATION forming part of Letters Patent No. 513,858, dated January30, 1894.

Application filed December23,1892. Serial No. 456,144. (No model.)

To all whom it may concern: Be it known that we, EDWIN ADAM and MARTINO. REHFUss, citizens of the United States, both residing in the city andcounty'of Philadelphia, State of Pennsylvania, have invented a new anduseful Improvement .in Method of and Apparatus for-Gharging andCombining Wort, Liquors, 850., with Carbonic-Acid Gas, which improvementis fully set forth in the following specification and accompanyingdrawing. 4

Our invention relates to a process of charging and treating fermented orunfermented wort cordials, distilled liquors or other liquids withcarbonic acid gas, which consists in drawing liquid from a tank,releasing it of pressure, then charging the same with carbonic acid gas,subjecting the charged liquid to a high pressure, then reducing the saidpressure.

It further'consists in displacing liquid from a high to a low pressure,or vice versa, then releasing the same of said pressures, charging thesaid liquid with carbonic acid gas, then compressing and combining thecharged liquid under high, or combined high and low pressures while inmotion, and maintaining the said high or low pressure after charging.

The drawing represents a perspective View in section of a buildinghaving in apartment or station 1, apparatus embodying our invention. 2,3, and 4: represent the cellars of said building. 5 and 6' are thestorage roomson the first floor, and 7, 8, and 9 are the storage roomson the upper floor, it being evident that other rooms may be employed.

Referring to the drawing: Adesignates the releasing and expanding tank,and B designates the high pressure combining and regulating tank.

T designates the low pressure combining vats or vessels.

0 designates the charging apparatus which has its chamber thereinsimilar to what is shown in the. drawings of the application for LettersPatent filed ,by us on the 3d day of December, 1892,Serial No.453,945,said appa ratus having connected with it the pipes D, E, F, andG, the pipe D leading from the cyl- 5o inders or tanks H, which containcarbonic acid gas. The pipe E leads from the bottom of the vessel B. Thepipe F leads from the injector J, connected with which is a pipe Kleading from the top of the vessel A. The pipe G leads from the bottomof said vessel A, all as substantially shown in the aforesaidapplication.

M designates a pump which is connected with the charging apparatus bymeans of a pipe N. v I

P designates a pipe which leads from the pump M to the vessel B.Connected with the bottom of the vesselAby means of a pipe Q, is a lowpressure regulating cylinder R,With which is connected the pipe S, thelatter leading to the lower ends of the low pressure combining vats orvessels, T, and opening into the same. Leading from the heads of saidlow pressure combining vats or vessels T is a pipe U, which is connectedwith the upper end of the vessel B. The low pressure regulating cylinderR is provided with a liquid pressure gage V, safety valve V, valve orcock V and the pipe Q, has a regulating valve W connected therewith. Thevessel A is provided with a gas pressure gage X, safety valve X, valveor cock X adjustable blow-0E valve X valve or cock X and a vent valve Y.The vessel B is provided with a liquid pressure gage Z, safety valve Z,valve or cook Z and the pipeU has a regulating valve B connected withit. The pipe D and connections of the same with the cylinders ortanksH,and the pipes S, U, D, K, P, G, are each provided with a valve or cock.

The operation is as follows: The vessels B and T are filled with aliquid to their utmost capacity, and the vessel A is only partiallyfilled with a liquid. All of the cocks or valves are opened, and thepump M is started, whereby all air is expelled through the vent valve Y.A hydraulic pressure is then created on the liquids in the high and lowpressure combining and regulating vessels B and T by means of thereleased liquid coming from the releasing and expanding vessel A,through the pipe G, into the end chamber of the charging apparatus G,then through the pipe N to the pump, and from thence through the pipe Pinto the vessel B, faster than the liquid that is forced out from saidvessel B through theregulating valve B, thereby causing a high pressureon said liquid in the vessel B. The

liquid is then forced under said pressure from said vessel through thevalve B, and through the pipe U into the low pressure combining vats orvessels T, and through the pipe S into the low pressure regulatingcylinder R, and through pipe Q and regulating valve W, the displacedliquid passing through said valve W being discharged into the releasingand expanding vesselAwhere it is released of pressure. The valveWregulates the low pressure as desired, in the low pressure vats orvessels T. For high pressure, the pump is started, and the regulatingvalve B is gradually partly closed until a hydraulic pressure of saytwenty pounds isindicated on the gage Z, the speed of the pump beingkept up. For low pressure, the regulating valve W is gradually partlyclosed until a hydraulic pressure of say ten pounds on the liquid inthelow pressure combining vats or vessels T is indicated on the liquidpressure gage V. This at the same time causes the hydraulic pressure onthe liquid in the vessel B to increase from twenty to say twenty-fivepounds. By thus operating with these pressures, there is obtained theadvantage of a full stream of liquid discharging into the releasing andexpanding tank A, and a higher or lower pressure may be obtained bymeans of the valves B, W, and the speed of the pump M. After havingregulated the high and the low pressure, then the main flow of carbonicacid gas is turned on, the same passing through the pipe D into themiddle chamber of the apparatus 0, and then charging into the liquidcoming from the vessel B, through the pipe E into the inner chamber ofsaid apparatus, the said charged liquid and gas being then sprayed ormixed into the liquid coming into and through the end chamber of theapparatus 0 from the vessel A, through pipe G, and passes through thetube N to the pump M, from whence it is forced through the pipe P intothe liquid under a high pressure in the vessel B, where the chargedliquid and gas becomes compressed and thoroughly combined, it at thesame time displacing under said pressure, a portion of the highcompressed and combined liquid into the low compressed liquid in thevats or vessels T, where it combines with its carbonic acid. gas withthe low compressed liquid, at the same time displacing under pressure, aportion of the low compressed and combined liquid in the vessel A, whereit is released and expanded of its pressure and uncombined carbonic acidgas. This process is continued until the liquid in the vats or vessels Tis sufficiently charged with carbonic acid gas, when then and there, itis confined under pressure until itissuificiently combined,when it isready to be handled for further use, or put into small packages.

We are aware that we have our application Serial No. 453,945, filedDecember 3, 1892, pending, which is in part similar in construction tothis application, the distinction however being evident, as in thiscase, we apply an additional tank or vessel, and methods for producing alow pressure on the liquid in said vessel after the same has beensubjected to a high pressure. This method being for the purposeofcharging liquids with carbonic acid gas quickly in vats or casks whichwill not stand ahigh pressure, as herein stated, the liquid after beingcharged with carbonic acid gas is subjected to a high pressure in atank, then reduced to a low pressure in said vats or casks, said vats orcasks containing pipes or branches having perforations or small openingsfor the purpose of distributing the charged liquid in the same.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. Theprocess of charging and treating a malt or other liquid withcarbonic acid gas, consisting in drawing the liquid from a tank andreleasing it of pressure, then charging the same with carbonic acid gas,subjecting the charged liquid to a high pressure, then reducing thepressure and returning it thus reduced to the said tank from which theliquid was drawn, substantially as described.

2. The process of charging and treating a 95 malt or other liquid withcarbonic acid gas, which consists in drawing liquid from a tank,releasing the liquid thus drawn of pressure, then passing the same intoand through a gas charging apparatus where it is mixed with I00 a smallportion of liquid highly charged with carbonic acid gas, and subjectingthe whole to a high pressure, and then reducing the pressure on saidliquid, substantially, as described.

3. An apparatus consisting of a releasing tank, a gas chargingapparatus, a high pressure combining tank, and pipes connecting saidapparatus and tanks, a low pressure combining vessel, and a pipe havinga pressure no reducing valve leading from said high pressure tank tosaid low pressure vessel, substantially as described.

4. An apparatus for the purpose set forth, having a releasing tank, agas charging apn5 paratus, high and low pressure combining vessels, andpipes connecting said devices with suitable attachments for regulatingboth high and low pressures in said vessels, and means for creating thesaid pressures in said :20 vessels, substantially as described.
